End mill geometry boosts trochoidal milling

Emuge Corp. has released Trochoidal End Mills, a new line of solid-carbide end mills with geometry and chipbreakers specifically designed for trochoidal milling.

These tools increase metal removal rates and enable fewer toolpaths to be used, while enabling a high axial depth of cut of up to 4xD, the company reports. They were developed specifically for advanced milling strategies available in modern CAM software to optimize the calculation of milling paths and avoid unproductive tool motion.

The end mills feature low vibration characteristics such as variable spacing, variable helix angles, and improved microgeometries, along with new, high-performance coatings of TiN/TiAlN or AlCr and a sub-micrograin carbide substrate. In addition, the newly developed chipbreaker geometry reduces axial pullout force and minimizes the risk of chip buildup in pockets, because the smaller chips are removed with compressed air or coolant.

They are available in two cutting geometries: Jet-Cut™ for both roughing and finishing in steel applications, and Coolant-Through TiNox-Cut™ for roughing in tough materials such as INCONEL® alloys, titanium, and stainless steel.

Standard and long-length rougher/finishers with flute length/diameter ratios of 2-to-1, 3-to-1, and 4-to-1 are available.
